I have seen pix of Trianga and Coglan alcohol stoves but it sounds like a fun DIY project to make one. There are many Youtube videos showing many variations. Has anybody made one?

I don't intend to use it for any multi-day canoe trips---more like daytrips when a nice cuppa would be good, for eg. when paddling, hiking, fishing

I'm a bit puzzled re the purpose of the 'inner wall' i.e the piece made cutting a sheet of Al from the middle part of the can.

I've made a few different fancy feast stoves for people.

Not really my thing but not much of an investment either. I just never feel too at ease with a pot balanced on a small tin of flammable liquid that's on fire.

I've made a couple of pop can stoves. They are easy to make and cost literally nothing.

They also work shockingly well. I was really surprised by the heat output. I have used naptha stoves all my life and I always thought alcohol was a much slower way to cook. It isn't. The biggest disadvantage is that there is no control, it is either on or off. However you can add a piece to damp it down a bit, I just haven't made one yet. For boiling water or one-pot meals it is fine. Really effective to use in conjunction with a pot cozy.

Inner wall: once the stove warms up, after about a minute depending on the temperature, the fuel is drawn up between the walls and flames shoot out the holes around the rims. Works much better that way.

I think they are perfect for backpacking because the stove weighs only a few grams. Bring a couple if you want. The fuel is also cheap and available at any hardware store (methyl hydrate).

Although I love my Svea 123 dearly, for backpacking this really is a great way to go.

Kinguq.

We make those with the Scouts - great fun. And you can really geek out on hole size and hole patterns - at one point I was doing heat tests with different patterns and sizes but I did not do a great job of documenting my results, unfortunately.

Also if you use one of the jumbo beer cans like a 1L can you get a bigger stove. If you take care and cut very precisely and put it together with epoxy you can make some pretty impressive stoves.

Should also mention that you have to use a pot stand and wind screen with these stoves. There are lots of plans on the web. The stoves are very sensitive to wind.

I have an old Sigg pot kit for the Svea and the windscreen from that just happens to work perfectly as a combined windscreen and pot stand for these stoves.

Thx guys. I am 'contemplating the variables'. . One other key variable is the possible use of absorbent material---I have seen fibreglass being suggested. The advantage, as I see it, is that it reduces the risks of major spillage. I guess it makes tha fuel burn more slowly. If so, I guess I will need to increase the stove size to compensate.

Yeah I never really understood why some people put stuff inside but I guess your explanation makes sense.

I assume that's the main reason. I have watched, or half watched, quite a few Youtube videos and they tend to be a bit short on design principles but very looong on the fab process! Nothing like watching some guy punch oodles of holes in the rim of a beer can!! I guess I should be thankful that they posted.
